New UITabBarController design on iPad is not yet supported. It is adaptive, so need inspect the trait collection most likely. It seems iPad simulator is completely broken as of beta 1, so this task will have to wait for Apple to not suck this badly.

Hello,

Is the popup bar always attached at the bottom of the view in Apple Music?

[LeoNatan]

@iDevelopper do you mean on iPad? I’m not sure.

[iDevelopper]

Yes, on iPad.

But since yesterday I found it should be the case at 5m30:

[LeoNatan]

Thanks. So it looks like iOS 17 (there wasn’t a tab bar in 17, only sidebar). It’s the look I intend to support, but once a more stable simulator is released.

[LeoNatan]

Floating tab bar is now supported:

The only issue I see currently is with the new UITabBarController.setTabBarHidden(_:animated:) method, but it seems so broken as of beta 3, I am not yet willing to invest time into supporting it. It’s a small animation breakage when using animated: true.

Hello @LeoNatan !

What about hidesBottomBarWhenPushed?

- (void)hBWT:(NSInteger)t iE:(BOOL)e d:(NSTimeInterval)duration

is no longer called by the system.

[LeoNatan]

Hello!

Is this something new? I am on iOS 18.1 beta, and it still works.

[iDevelopper]

I am on 18.0 beta 5. Apple doesn't offer me 18.1! Any idea?

[LeoNatan]

Not sure yet. I'll check to see if there is a new Xcode with an updated SDK, and then debug. There are two options, either Apple renamed the method, or they hid it from the ObjC runtime. The latter will be more hard to fix.

[iDevelopper]

It seems that 18.1 is not compatible with iPhone 14 Pro.

[LeoNatan]

The current 18.1 build is older than the 18.0 build anyway.

[iDevelopper]

I have Xcode 16 beta 5 (build 16A5221g) and I can't find 18.1 simulators

I found a fix. But Apple’s -[UITabBarController isTabBarHidden] is broken (by Apple) in latest beta. 🤦‍♂️

[LeoNatan]

I pushed, play around with it @iDevelopper

[iDevelopper]

Thanks, I'll try. May I ask how you find this as I can't find any up-to-date Apple Runtime Headers. I know you have a repository but you don't update it anymore.

[LeoNatan]

It’s not easy to maintain anymore. Instead, I use runtime inspection. There is _methodDescription and _ivarDescription.

[iDevelopper]

Thank @LeoNatan!

It works!

[iDevelopper]

Why do you say that isTabBarHidden is broken? What is not working? What would be the expected result for you?

[LeoNatan]

isTabBarHidden returns false for instances where a controller with hidesBottomBarWhenPushed=true was pushed. The tab bar is hidden, but isTabBarHidden returns false. This broke in the latest beta, and worked correctly before.

According to Apple, in the feedback I files, this is the expected behavior.

Hello,

According to Apple, in the feedback I files, this is the expected behavior.

More details from them? How do they explain this is the expected behavior?
