iOS Question Updated to iOS15, now top bar goes black when switching apps

[bjones]

Has anyone noticed the top bar on their app going black when switching apps after updating to iOS15?

 

[Semen Matusovskiy]

Nothing changed on my iPhone 6s Plus (BTW, I did not hope to receive IOS 15).

Try the simulator.

I'm running iOS 15 for several months now and didn't see such behavior.

I have the same problem.
Also the navigation bar and the toolbar will be black.

Looks like dark theme. Which version of B4i are you using?

 

[André Groeneveld]

B4i = version 7.5
Local Macbook / macos 11.6 / parallels windows 10
Xcode 13
Ios 15

1. Can you reproduce it in a small project?
2. Have you tested it on a real device?

 

[André Groeneveld]

1 = yes
2 = Yes

I'm running iOS 15 for several months now and didn't see such behavior.

I thought iOS 15 just available recently. ?
I have no WiFi so I am not rushing to update. I will wait for a few months or wait version 15.1 come out only update. ?

Edit: You mean developer beta?

 

[André Groeneveld]

This is te solution in Xcode, but how to use it in b4i?

 

[Semen Matusovskiy]

A problem is exactly in XCode 13, not in IOS 15. Guess, there is a reason to wait an update and to use XCode 12.5 just now.

XCode 12.5

But this version will not work with iOS 15

 

[Semen Matusovskiy]

Do you mean simulators ? It's not a problem for me, because a smartphone has IOS 15.

I tried API (overrideUserInterfaceStyle). Works fine using XCode 12.5 (in simulators and in iPhone). But troubles in XCode 13.
IMO, it's simply a bug (whong description of Light Theme). BTW, real Dark theme works fine in XCode 13.

 

[Erel]

You should use Xcode 12 for now. It is compatible with iOS 15.

 

[André Groeneveld]

Thanks, the version Xcode 12.5 works fine.
I am happy to use b4x, also for android and pc!!
