I am looking for a way to get customer ratings without reviews via the App Store Connect API. The customerReviews resource seems to only return ratings which are accompanied by a review. Is there maybe another way I am missing?

Is there a way to view the opt-in rate via the API? I have been unsuccessful in finding one.

We have found that on iOS 26 beta some of our app icons built from an Xcode 16 asset catalog containing a single 1024x1024 .png file have a Liquid Glass effect applied to them while others have not. The documentation states that If you choose not to use Icon Composer, you can still use an AppIcon asset catalog in your project containing individual app icon images and let the system apply the Liquid Glass material. and If you prefer, you can take advantage of the system’s automatically generated treatment that is applied to all app icons. Is there any insight into how the system treats app icons that have not yet been updated with Icon Composer?

I want to track down which part of an app contacts a given domain listed in its App Privacy Report. Following the instructions given here I am able to capture a packet trace, but traffic to the domain in question is encrypted using QUIC. Is there a way to insert e.g. mitmproxy into the capture process in order to get hold of the SSLKEYLOGFILE so that I can decrypt the traffic?

One of our apps (built with Xcode 26.1.1 and distributed via TestFlight) crashes upon launch on iOS 17 with Exception Type: EXC_BAD_ACCESS (SIGKILL) and Termination Reason: CODESIGNING 2 Invalid Page. I have never seen this before. Any pointers? On iOS 18 & 26 this does not happen btw.

The header documentation for the (deprecated) LAContext.evaluatedPolicyDomainState property contains the following: @warning Please note that the value returned by this property can change exceptionally between major OS versions even if the state of biometry has not changed. I noticed that the documentation for the new LAContext.domainState property does not contain a similar warning. I also found this related thread from 2016/17. Is the domainState property not susceptible to changes between major OS versions? Or is this generally not an issue anymore?

For testing purposes we have code that calls SecTrustEvaluateAsyncWithError() with a trust object containing a hardcoded leaf certificate and the corresponding intermediate certificate required to form a valid chain. Because the leaf certificate has since expired we pass a date in the past via SecTrustSetVerifyDate() at wich the certificate was still valid, but trust evaluation fails: Error Domain=NSOSStatusErrorDomain Code=-67825 "“<redacted>” certificate is not standards compliant" UserInfo={NSLocalizedDescription=“<redacted>” certificate is not standards compliant, NSUnderlyingError=0x600000c282a0 {Error Domain=NSOSStatusErrorDomain Code=-67825 "Certificate 0 “<redacted>” has errors: Certificate Transparency validation required for this use;" UserInfo={NSLocalizedDescription=Certificate 0 “<redacted>” has errors: Certificate Transparency validation required for this use;}}} I know that App Transport Security enforces Certificate Transparency by default, but is there a way around that here?

The CA/Browser Forum has voted (cf. https://groups.google.com/a/groups.cabforum.org/g/servercert-wg/c/9768xgUUfhQ?pli=1) to eventually reduce the maximum validity period for a SSL certificate from 398 days to 47 days by March 2029. This makes statically pinning a leaf certificate rather challenging. What are the consequences for App Transport Security Identity Pinning as it exists today?

I am trying to use the NFCTagReaderSession to SELECT the master file of a ISO 7816 smartcard by sending a corresponding NFCISO7816APDU after connecting to the card, but I am running into errors: Error Domain=NFCError Code=2 "Missing required entitlement" UserInfo={NSLocalizedDescription=Missing required entitlement} Error Domain=NFCError Code=103 "Session invalidated" UserInfo={NSLocalizedDescription=Session invalidated} I know that in order to communicate with a NFCISO7816Tag I need to declare the supported AIDs in the Info.plist, but what am I supposed to declare here?

I am trying to retrieve the numbers displayed in "App Analytics" under "Metrics" > "Active Devices" using the API. Since there does not seem to be a dedicated report for this metric I am using the daily "App Sessions Standard" report and by looking at the "Sessions" field I am able to recreate the numbers displayed for the "Sessions" metric. However if I try to infer the active devices by looking at the "Unique Devices" field my numbers for individual days are in the same ballpark (deviations may be attributable to privacy reasons?), but the total number of devices is way off. Is there a better way to recreate this metric?

On iOS Bundle.main.preferredLocalizations returns the list of languages the application bundle supports in user-preferred order with the first element being the language the application is running in. Additionally Locale.preferredLanguages returns the list of languages in the order they are presented in Preferences.app &gt; General &gt; Language &amp; Region &gt; Preferred Languages with the first element being the user's "primary language" (i.e. the language the system is running in). However this only seems to be true unless the user has chosen a per-app language which is different from the primary language in which case Locale.preferredLanguages.first is equal to Bundle.main.preferredLocalizations.first - regardless of the latter's position in the Preferred Languages list. Furthermore this seems to change depending on the value of the "AppleLanguages" key in the User Defaults' global domain (see c.f. https://stackoverflow.com/a/42648166). Is this behaviour documented anywhere? Addendum: I know that according to https://forums.developer.apple.com/forums/thread/718512?answerId=733680022#733680022 AppleLanguages is an implementation detail, not something that’s considered API. Locale.preferredLanguages is API, though.

The sample code uses a static variable of the PeripheralViewController class to account for congestion in the BLE stack - which is frowned upon by the Swift 6 compiler. Why does this variable need to be static in the first place?

Suppose there is a key in the keychain that is protected by an ACL which specifies .userPresence as its access control - is it possible to prevent the user from being prompted to authenticate with biometrics and to force authentication via the device passcode instead?

I have been bitten by this repeatedly so I am finally going to ask: Is there a way to infer an error from its localizedDescription only? It sometimes happens that a user reaches out for support with just a localized error message, but no error code or error domain and it is really hard to correctly guess what the non-localized description may have been in order to search for it. For example I know from experience that "Der eingegebene Benutzername oder das Passwort ist ungültig." is the German localization of "The user name or passphrase you entered is not correct." which in turn is errSecAuthFailed (aka. -25293). It would be really helpful to be able to just look this up somewhere...

I am trying to implement BLE communication between installations of an iOS app and I am following Transferring Data Between Bluetooth Low Energy Devices since the data I need to transfer exceeds the 512 byte limit for attribute values. I already have this working based on an older version of the app, however after I integrated with the mainline of development I am getting CBATTErrorRequestNotSupported which seems to be caused by OSStatus 65535 (which is kBluetoothSDPErrorCodeReservedEnd, but that is documented to not even be present on iOS). So it seems that a change on our end is causing these errors, but I am completely stumped as to what change that might be. Is anyone able to enlighten me?
