Is this setup possible / have a solution: There is a .xcframework F, which uses a 3rd party library, lets call it L. There is an app which uses the xcframework The app also uses L Both the app and F use SPM to integrate L F is using L for its own internal purposes. F is providing some functionality to the app. How it implements that ideally should be a black box from the app's perspective. The app also happens to use L for its own purposes. I can't get this set up working, always get warnings about duplicate symbols when running the App. This will presumably be due to the fact there are separate copies of L in both F and A. So how can that be eliminated? Can F not statically like to L and use the App's version of L at runtime? If so how can Xcode be configured so that F can actually compile? Or vice versa - can the App not statically link in its own copy of L and use that in the framework? If so, similar questions, how to configure Xcode to set this up? I can't believe this is an obscure use case, yet after days of searching and reading documentation I can't find any solution. Note that I was able to get this going when the app and the framework used Cocoapods to integrate L, but I just can't do similarly if the use of Cocoapods is replaced with SMP. When using cocoapods, within the frameworks Xcode section, the pods framework is set to Do Not Embed. This is probably the vital difference between the working Cocoapods implementation and the not working SPM solution. However, when using SPM Xcode doesn't present any option to either embed nor not embed the dependency. Why not? Can it somehow be set to not embed?

I just noticed this today while building a React Native app. Anybody else seen this and know what it means/how to track it down/how to fix it

A message filter extension is only forwarded SMSs by the OS for filtering, iMessages aren't. But what is the situation with RCS messages? Will they be filterable by a message filtering extension?

If an Xcode project has some compiler flags set in Build Phases / Compile Sources, then is it possible to have those enabled if scheme A is selected and disabled if scheme B is selected. Same question for things in Build Settings, such as Other Compiler Flags. I suppose it could be achieved by having two targets, one with things enabled and one without, but for a very large complex project, duplicating targets is not necessarily an easy thing to do.

I've got several Xcode iOS projects and in the Editor menu section there are dozen's of options, as in the diagram. However if I create a new iOX Project (with Xcode 16.2) look at how sparse the Editor menu is. Why is that, why do they appear for other projects but not for a new one and why are the contents different?

If I create an Xcode (version doesn't matter, 16.N )project of type framework then install some dependencies using SPM. Then within the Frameworks and Libraries section, the Embed part is empty. This doesn't happen if the project type is app rather than framework. If I want to set this to embed or not embed then how can this be done if its not even visible, for that matter how can I tell what it is set to even?

I've got an iOS app with lots of extensions, some of them complex and doing a lot of stuff. After a bug I'd like to be able to use OSLogStore to get a holistic picture of logging for the app and its extensions and send that to a debugging server to retrospectively view logs for the app and its extensions. The constructor is OSLogStore.init(scope: OSLogStore.Scope), however scope only has one value .currentProcessIdentifier. Implying if that is called from within the app it can only get access to logging for its process only. I tried it out to confirm this is the case - if I log something in an extension (using Logger), then run the app with code like this:  let logStore = try! OSLogStore(scope: .currentProcessIdentifier)  let oneHourAgo = logStore.position(date: Date().addingTimeInterval(-3600)) let allEntries = try! logStore.getEntries(at: oneHourAgo)       for entry in allEntries { look at the content of the entry Then none of the entries are from the extension. Is there anyway from within the app I can access logging made within an extension?

Within Xcode's settings location section is a drop down menu to switch between setting the derived data location to be default, relative or custom. However its a global setting. I work on more than one project simultaneously, and for one of them I want the location set to relative, but default for all the others. Is there any way of achieving that?

If an iOS app gets terminated by watchdog due to, for example, hanging the main thread, is that considered to be a crash or something different. I'm asking because, according to google and AI, Crashlytics can detect and report these,but in my experience it does not. If I deliberately cause a watchdog termination by for example sleeping on the main thread for a long time then these never appear in Crashlytics. I know Apple folks here don't comment on non Apple software, so I'm not asking about Crashlytics, just wondering and interested about watchdog timeout terminations and how they differ from a "regular" crash.

I want to release a Framework F, containing several other frameworks (such as Realm, Appetitive, Cocoalumberjack, PhoneNumberKit) for use by app A. According to this article: https://medium.com/@bittudavis/how-to-create-an-umbrella-framework-in-swift-ca964d0a2345 They write, without referencing a source: "Although Apple discourage creating umbrella framework". Is that true, do Apple discourage umbrella frameworks, if so why and is it a very strong discourage or a mild one? If not discouraged, then how can this be achieved with Xcode 16? I've been attempting to follow a few tutorial to achieve this, such as https://medium.com/john-lewis-software-engineering/adding-a-third-party-framework-inside-a-first-party-framework-in-xcode-3ba58cfd08da however so far without any success. This last article mentions the Link Binary With Libraries section, which doesn't exist in Xcode 16. There's the Frameworks, Libraries, and Embedded Content section where I have been attempting to add the frameworks into my Framework F (choosing Embed without Signing). I'm able to successfully build Framework F, but when app A attempts to use it (adding F to the Frameworks, Libraries, and Embedded Content section with option embed and sign, or embed and don't sign, makes no difference) then I get run time errors about the umbrellaed frameworks not being able to be found.

I've got an app where I want to split its Model code into a framework (.xcframework and .framework for debugging) so that it can be used by more than one app. The code has dependencies on 3rd party code, which are installed via pods. During the conversion process I keep running into the same issue which manifests with all the 3rd party code - which is that the majority of its api can be used (something like 80-90%) but for the remainder there is a linker error at runtime showing undefined symbols. I have this problem with CocoaLumberjack,RealmSwift, PhoneNumberKit and more. Its very quick and easy to reproduce the issue with a minimal framework and minimal app, below I'll describe how a minimal setup using CocoaLumberjack reproduces the issue: From scratch, I use Xcode to create a framework project, run pod init, then modify the pod file to be: platform :ios, '16.0' workspace 'TheFramework' project 'TheFramework' target 'TheFramework' do use_frameworks! pod 'CocoaLumberjack/Swift', '3.8.5' end post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '16.0' config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES' end end end Then I add source code: import Foundation import CocoaLumberjack public class AClassInTheFramework { public class func aMethod() { let consoleLogger = DDOSLogger.sharedInstance DDLog.add(consoleLogger, with: .debug) DDLogDebug("Some logging") } } Within the Xcode project, Build Libraries for Distribution is set to Yes, I also add that line to the pod file in case CocoaLumberjack isn't set similarly. In the Framework's Xcode General section, Frameworks and Libraries contains Pods_TheFramework.framework set to Do Not Embed. In the Build Phases section, in the Link Binary with Libraries section, Pods_TheFramework.framework is set to required. Next I create an Xcode app template, run pod install, and edit the app pod file to be: platform :ios, '16.0' workspace 'AppUsingFramework' project 'AppUsingFramework' target 'AppUsingFramework' do use_frameworks! pod 'CocoaLumberjack/Swift', '3.8.5' end post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '16.0' end end end I build the framework, and drag and drop it into the app. I add the following code to the app's delegate: import TheFramework ... AClassInTheFramework.aMethod() The App's target has the following linkage settings: When I build and run the app, there is the following error: If I change the source code in the framework to this: public class AClassInTheFramework { public class func aMethod() { let consoleLogger = DDOSLogger.sharedInstance DDLog.add(consoleLogger, with: .debug) // DDLogDebug("Some logging") } } Then there is no error and the code runs successfully. This illustrates the problem I've encountered with all the nested frameworks - in this particular case calls to DDLog.add() don't result in an error but calls to DDlogDebug() do, and that has been mirrored with other nested frameworks (for example with Realm, opening a database, adding, finding,retrieving an item all works without a problem, however attempting to use Realm's Results<> API results in a similar symbol not found error). Additionally note that the identical CocoaLumberjack code can run fine when used directly from within the app, i.e., if I add the following code to the app: import CocoaLumberjack func useCocoaLumberjackDirectlyFromWithinApp() { let consoleLogger = DDOSLogger.sharedInstance DDLog.add(consoleLogger, with: .debug) DDLogDebug("Some logging") } useCocoaLumberjackDirectlyFromWithinApp() Then it runs, i.e. DDLogDebug() can be successfully called from within the app, its only when its called via the framework that the error occurs. Why might I be encountering these issues? I'd have thought either I'd be able to use 100% of the nested framework's public api, or 0% of it (is something is not configured correct), not ~80% which is what I am encountering. Any ideas? TIA

In the documentation for the example Live Caller ID server (https://swiftpackageindex.com/apple/live-caller-id-lookup-example/main/documentation/pirservice/testinginstructions) there is an example service-config.json. file shown (without thorough documentation). That config file, and the whole of the instructions, center around there being two datasets of numbers: block and identity. My question is - is it possible for more than one dataset to be specified i.e. for block1 and block2 to be specified? The use case for this would be - suppose the Live Caller ID server has a set of numbers it has identified as being nuisance callers and so it lists these in the block section. However user A might want all these nuisance callers to be blocked but user B does not. Therefore the Live Caller ID extension on the handset would need to use a different dataset on the server so that user A's calls from a set of numbers is blocked, but user B's are not. Note that I'm not suggesting that the Caller ID server should be capable of storing individual user's preferences. All that would be required would be two data sets: one where blocked content is none and and one where blocked content is some. Then a user/app could switch between them as indicated by the user. Is that possible? If the database structure and service-config.json etc. is not configured to permit that, then could two different servers be set up to achieve this instead? i.e. so the server url specified in the app's extension can be set at run time and not at compile time?

With the Live Caller ID example server, the caller lookup dataset is defined in an input.txtpd and processed by running a ConstructDatabase command which creates a block.binpb and an identity.binpb file. In other words, a static input file is being processed into static block and identity files. However, in the real world, the data content for identified and blocked numbers is something which is in a constant state of flux and evolution, as new numbers becoming available, old ones become stale, numbers which were initially considered safe change into being considered malicious etc. etc. Is the example server just that, merely an example using fixed datasets, and an actual production server is able to use live every changing data to formulate its response back to the iPhone OS query? Here's a concrete use case - suppose it's a requirement to permit US nanp numbers but to block anything else. The total number of non US nanp numbers is so large and ever changing that it would be unfeasible to attempt to capture them in an input.txtpd file and then process that, and then to re-capture and re-process it endlessly. Instead what would be required is the ability for the Live Caller ID server to evaluate at query time, using a regular expressions for example, if a number is nanp or not. Is this possible?

I've got an existing app which is using some 3rd party xcframeworks within its app extensions (for example within a Notification Service Extension). Within the target for the app extensions there is a Frameworks and Libraries section where the xcframework was dragged and dropped into. However now I want to create a new project and do a similar thing, within the app's target there is a Frameworks and Libraries section, but when an app extension target is created, Xcode is not adding a Frameworks and Libraries section. There is a Link Library with Binary section, however this doesn't have an embed section (where you can select to embed, don't embed, embed without signing etc.) and I get build error trying to drag and drop the xcframework in here. Where id the Framewoks and Libraries section go for app extensions for projects created with Xcode 16? How can this section be added?
