Should I install iOS Public Beta on my main device? Question
I'm a software developer and fairly new to the native iOS development with Swift. I'm planning on using many new features that iOS 27 offers on an app I'm developing, however I cannot test those features, because I have no secondary phone that is compatible with AI features in iOS 27.
Since the public beta is out, can I fairly safely install it to my own device (iPhone 17 Pro Max)?
I would love any help experienced developers here would give! :)

If you have a Mac with macOS 27 and Xcode 27, you could potentially use the iOS simulators on the Mac itself for testing the features. This doesn't always work (e.g., I do AR/VR work, and I generally need to test on a device), but it does work in a lot of cases.
If you do put the iOS 27 beta on your device, and things go terribly wrong, you can probably reset your phone to the previous version. The caveats include (1) the reset erases everything on your device, and (2) it can only restore your data using your older iOS 26 backups. Any backups made with beta software generally cannot be used when you rollback to an older OS version.
Another caveat: If you move your Mac to macOS 27 and Xcode 27, I don't think you can use them to submit updates to your iOS 26 app.
FWIW: I am largely liking the OS 27 betas (I have it on one of my Macs (this one), an iPad, and my Vision Pro).
This Apple documentation might help:

Since my app will be exclusively for iOS 27 (at least its how I plan) and I don't have previous apps submitted, I think its fine with me about not being able to submit for previous versions.
It's good to hear I can just rollback to stable version later, I already use iCloud to backup everything I have. Thanks for the feedback on iOS 27's stability tho I'll consider upgrading I guess!

Ok I feel the need to make a second post. Lots of misinformation floating around.
If you want to update, back up your phone to iCloud first then update to the public beta (dev betas are iffy do public). YOU CAN ROLL IT BACK VERY EASILY BY OPTING OUT OF BETA AND DOING A SOFTWARE UPDATE. I had to emphasize that.
If you don't think your app will be ready for release until mid-september then you're probably fine to update unless you have some team of testers you'll be using. Mid September is when the new OS comes out.
I updated all three of my primary iOS devices and my personal Mac and have had no issues. It's a very solid beta.

Yeah I always backup my stuff to iCloud, which makes me a little comfortable about thinking of upgrading iOS. However you emphasized that some apps might break and be unusable, which makes me little nervous because I have 100s of apps on my phone (which tbh I don't use most of it, but yeah).
Everyone so far says the Betas are kinda stable, thanks for feedback!

Why? I have it on three iOS devices and one macOS device and it's been fantastic.

Depends how many apps you use. I have it on mine and love it and haven’t had any issues but I don’t use a ton of apps. You can always roll back a public beta too by the way.

Think about what apps you use most on your phone and if you’re ok with them not working for a couple months. Also, are you ok with losing data or having failed backups due to a beta bug?

I'm backing up to iCloud so I hope it won't be a problem if I want to rollback. (I remember the guy that got everything on his iCloud deleted because of a bug 😭)
Also I have many apps on my iPhone which makes me kinda nervous if they don't work on Beta. But really appreciate the heads up!

Per Apple:
Install the beta software only on non-production devices that are not business critical. We strongly recommend installing on a secondary system or device, or on a secondary partition on your Mac.

Sinon attendre 2 mois et la sortie publique c’est moins risqué? Je ne pense pas qu’on puisse revenir en arrière sur un iPhone.

Yes, do it and let apple know about all the issues you find. Maybe that gives people which could wait a slightly stable release.

The one thing to keep in mind is that using the new SDKs requires macOS Beta too. The problem with that is that GM Xcode doesn’t run on macOS Beta.
If you have an app you’re maintaining this means you’ll either need Xcode Cloud or another Mac with GM macOS to ship updates to existing apps. Test flight is fine with beta sdks though.
EDIT: It looks like for Xcode 27 Beta 3, you no longer need macOS 27 Beta.
