Illegal Configuration: Compiling IB documents for earlier than iOS 7 is no longer supported

Question

I recently updated to XCode 9. When I build the app it says "illegal configuration" for some storyboards in my pod files. I tried to recreate the storyboard files but it doesn't help.

Solution 1

XCode 9 will not support storyboards that are built for iOS version less than 7.

Try changing the Builds for in File Inspector to a higher version then Clean and Build.

See screenshot

Edit: Important info from @user435779 below: Restart XCode if the errors don't go away.

Solution 2

Simply set the deployment target to 8.0 + in General to fix this issue. No need to go through each xib file.

Solution 3

As storyboard in Xcode 9 will not support which is below iOS 7.0, so you need to update the iOS version in File inspector.

Hope it works!!!

I highly recommend setting Builds for to Deployment Target (v.m) (make sure your target is 7+)

I found I also needed to close and restart XCode after doing the Clean. No idea why. ymmv

@user435779 You were right, restarting did the trick. Clean then restart. Also, it works if you actually open all your xib files, one by one, and setting the Deployment Target manually, if not already set. Then clean and restart.

I had a bunch of xib files so changing each build for would have been a small challenge, but simply changing the Deployment Target worked fine for me. For laughs, it was set to 6.1! Lol.

I had a few random XIBs set to 7.x - no idea why. Thank you @user435779 - I needed to restart XCode to make it work. I'll add that to the main answer.

I cannot find "File Inspector" anywhere in "Xcode 9". Could you please provide a larger screenshot showing how to get there?

You set the target to 7.0, you would not have issues too! So if you want lower deployment target 7.0 is the lowest possible to avoid this Illegal Configuration issue.

I recommend that you choose the deployment target iOS version.

got error "This application does not support this device’s CPU type"

Don't know why but always restart the XCode does the Job.!

Even though the Deployment Target is set under General, the xib files can independently have their File Inspector -> Interface Builder Document section set to a separate Builds for setting that does not follow the General setting. This is especially true when you are re-using "code" or xib files across projects or from open source.

Excuse me, Can I know how you made or what stuff you used for that GIF animation in your MacOS?

Download the "Giphy Capture" software from the AppStore.

Thank you - I needed to open an old project and Xcode was beach-balling as soon as I tried to open the Storyboard to change the deployment target. Changing the Deployment Target for the whole project was the best solution for me.
