The Revolut app was written and tested for iOS 18, not iOS 26. If it doesn't work it's up to Revolut to fix the issues and release it when iOS 26 is released. This is precisely why you should never install the beta versions on your primary device. If you can no longer access your banking app, well...

The documentation is likely out of date, and you may want to raise a feedback report to Apple to have it updated: https://feedbackassistant.apple.com/ macOS Sequoia introduced the Passwords app, which meant you didn't really need to use Keychain Access anymore. However, as you've noticed, you do need it for some things. It's now in System > Library > CoreServices > Applications, but the easiest way to get to it is with Spotlight.

When you install a new version of the OS - especially a beta version - it has to do some extra work to index files and whatnot. That's why your phone might feel a little warmer than normal for a day or two. For a beta version there are extra processes enabled that allow Apple to record more info whilst the software is in beta. Those processes are not enabled in release versions. You just have to give it a little time to settle down. You also have to understand that you have installed beta software, and there are going to be issues. If you find something you think is a bug in the beta software, raise a feedback report here: https://feedbackassistant.apple.com/

Third-party apps, or ones supplied by Apple? If it's Apple's apps, then they're still in beta, but you can raise a bug report here if you like, to make sure Apple are aware of the issue: https://feedbackassistant.apple.com/ If it's third-party apps, like Uber or whatever, they have been written and tested to work with iOS 18, not iOS 26. There are going to be issues, and Uber etc. will update their apps in good time.

Is there an option for call screening? You mentioned that "it's turned on," so I assume you've enabled it in the Settings app somewhere? If so, call screening will be available on your 2nd-gen iPhone SE. The fact it's not working is probably a bug, and the fact you've raised it in the right place is the right thing to do. (Apple have never put a setting in the Settings app for a feature that simply isn't available on that iPhone. Imagine the customer complaints!)

If you've found a bug in the betas you need to tell Apple about it in the usual way, which is to raise a bug at: https://feedbackassistant.apple.com/ Posting it in these Developer Forums - which are primarily here for developers of third-party apps for Apple's platforms to ask for hints and tips on coding their apps - won't really do any good, as it will get missed. This isn't the place where Apple's actual, employed developers are hanging around waiting for bug reports. Please report issues in the correct place. Thanks.

Personally, I never update to the latest betas on my development Mac. If I did that I wouldn't be able to continue developing my existing apps in older versions of Xcode on a stable platform. I have a separate Mac that I use for betas. If you only have one Mac, then you could partition your drive, or use a virtual machine; either should work perfectly well.

Which OS is this on? Is it specific to a device, or all devices? Since you're raising a bug, please do it in the usual place, which is not these Developer Forums. This isn't where Apple's developers sit around waiting for things to do. This is where third-party developers ask each other for hints and tips on how to code their apps for Apple's platforms. Bugs can be raised at: https://feedbackassistant.apple.com/

Have you scrolled to the bottom? I mean, the very first sentence in that agreement is "PLEASE SCROLL DOWN AND READ ALL OF THE FOLLOWING TERMS AND CONDITIONS", so...

Removed. Last line of the "Window management" section: https://en.wikipedia.org/wiki/IPadOS_26

Please don't post screenshots of errors. Post the actual text. You can't search text in a screenshot, so if someone has this issue in future and this post has a solution, it won't come up. Also, it look like you need to move your app to use UIScene. This has been a known migration since about iOS 13. If you need a hint on how to do this, create a new project in Xcode and you'll see how the SceneDelegate is implemented.

Right. It's a beta. What you need to do when you find an issue in a beta version of the software is report the issue to Apple at: https://feedbackassistant.apple.com/ then post the FB number here. Bugs mentioned off-hand in a post on the Developer Forums won't get progressed because this is the wrong place for reporting issues. Posting issues about the betas in these Developer Forums just spams these forums, and pollutes what they're here for - they're for developers of apps for Apple's platforms to ask each other for hints and tips on coding.

Possibly because posting it in the Developer Forums is the wrong place? Raise a bug in the usual way at: https://feedbackassistant.apple.com/ then post the FB number here.

These are the Developer Forums, where developers of apps for Apple's platforms ask each other for hints and tips on coding. Your question is more of a product support one, so I'd suggest you ask it over at the Apple Support Forums. Thanks.

It's not a capability. You need to add it to your Info.plist file. Here's a screenshot of the relevant item you need to add - to the appropriate target - highlighted in blue: The 'Value' is a String key in quotes, and you need an InfoPlist.strings file for each supported language. The file contains descriptive text giving reasons why your app needs photo library access, or location access etc. Here's what mine looks like for the two keys seen in that screenshot: NSPhotoLibraryUsageDescription = "FILL THIS IN WITH THE TEXT THAT WILL APPEAR IN AN ACCESS PROMPT DIALOG"; "Privacy_UsageDescription_PhotoLibrary" = "FILL THIS IN WITH THE TEXT THAT WILL APPEAR IN AN ACCESS PROMPT DIALOG"; NSLocationWhenInUseUsageDescription = "SOME LOCATION TEXT GOES HERE"; "Location_UsageDescription_WhenInUse" = "SOME LOCATION TEXT GOES HERE";
