iOS 11.2 custom navigation bar infinite loop - ios

Question

Since the release of IOS 11.2 my app is encountering an infinite loop when pushing a view controller whose navigation controller has a custom navigation bar height. Did someone find the solution for this problem? Thanks.
-(void)layoutSubviews{
[super layoutSubviews];
float height = 42.5;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
height = 48;
}
imageView.frame = CGRectMake(0, 0, [[UIScreen mainScreen]bounds].size.width, height);
if(UI_USER_INTERFACE_IDIOM() ==UIUserInterfaceIdiomPad){
if(#available(iOS 11.0,*)){
self.frame =CGRectMake(0, 20,[[UIScreen mainScreen]bounds].size.width, 55); // this line provoke the infinite loop
for(UIView *aView in self.subviews){
if([NSStringFromClass([aView class]) isEqualToString: #"_UINavigationBarContentView"]){
aView.frame = CGRectMake(0, 10, aView.frame.size.width, aView.frame.size.height);
}
if([NSStringFromClass([aView class]) isEqualToString: #"_UIBarBackground"]){
aView.frame = CGRectMake(0, 0, aView.frame.size.width, self.frame.size.height );
}
}
}
}
}

I also had the same problem.
I solved by removing this
frame.size.height = customHeight
from layoutSubviews and then adding this
override var frame: CGRect {
get {
return CGRect(x: 0, y: 0, width: super.frame.width, height: customHeight)
}
set (value) {
super.frame = value
}
}
to my UINavigationBar subclass.
I left all other code in layoutSubviews as it was before. (nb)
