iOS 11 beta 9 empty keyboard keys

Question

I've got this annoying bug while compiling my app with Xcode 9 beta 6. it occurs on the simulator and on device. the numeric keypad is working.

any idea ?

Answer 1

This happens in GM seed as well.

This is caused by an internal iOS 11 issue when the following extension is implemented. Remove the extension and the keyboard is back.

UIView+TintColor.h

#ifndef UIView_TintColor_h
#define UIView_TintColor_h

#import <UIKit/UIKit.h>
@interface UIView (TintColor)
@property (nonatomic,retain) UIColor* tintColor;
@end
#endif /* UIView_TintColor_h */

UIView+TintColor.m

#import <Foundation/Foundation.h>
#import "UIView+TintColor.h"
#import <objc/runtime.h>

static char const * const tintColorKey = "tintColorKey";

@implementation UIView (TintColor)

-(UIColor*)tintColor
{
    return  objc_getAssociatedObject(self , tintColorKey);
}

-(void)setTintColor:(UIColor *)tintColor
{
    objc_setAssociatedObject(self, tintColorKey, tintColor, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}

@end
