My App always encounter with CoreAutoLayout invade
My SnapKit layout constraint as follow:
popBgView.snp.makeConstraints { make in
make.centerY.equalToSuperview()
make.leading.equalTo(assistantTeacherView.snp.trailing).offset(.isiPad ? -50 : -40)
if TTLGlobalConstants.isCompactScreen320 {
make.width.lessThanOrEqualTo(300)
} else {
let widthRatio = .isiPad ? 494.0 / 1024.0 : 434.0 / 812.0
make.width.lessThanOrEqualTo(TTLGlobalConstants.screenWidth * widthRatio)
}
bubbleViewRightConstraint = make.trailing.equalToSuperview().constraint
}
.....
popBgView.addSubview(functionView)
msgLabel.snp.remakeConstraints { make in
make.leading.equalToSuperview().inset(Metric.msgLabelHorizantalInset)
make.centerY.equalToSuperview()
make.trailing.lessThanOrEqualToSuperview().inset(Metric.msgLabelHorizantalInset)
make.top.equalTo(Metric.msgLabelVerticalInset)
}
functionView.snp.makeConstraints { make in
make.leading.equalTo(msgLabel.snp.trailing).offset(Metric.msgLabelFunctionSpacing)
make.centerY.equalToSuperview()
make.trailing.equalToSuperview().offset(-Metric.msgLabelHorizantalInset)
}
msgLabel and functionView superview is popBgView
However, when I try remove from superview for functionView, There is low probability crash:

I have printed __cplusplus that is "201402",and my build setting also is c++17.
If this issue cannot be perfectly solved that I have to change my MINDEPLOYMENT_TARGET to iOS 13
my code:
guard let drawable = view.currentDrawable else { return }
let renderPassDescriptor = MTLRenderPassDescriptor()
renderPassDescriptor.colorAttachments[0].texture = drawable.texture //There is a crash
renderPassDescriptor.colorAttachments[0].loadAction = .clear
renderPassDescriptor.colorAttachments[0].clearColor = MTLClearColor(red: 0, green: 0, blue: 0, alpha: 0)
error info:
MTLTextureDescriptor has height (9964) greater than the maximum allowed size of 8192. > validateTextureDimensions > validateTextureDimensions:1075: failed assertion `MTLTextureDescriptor has height (9964) greater than the maximum allowed size of 8192.'
please help:
I try to put a canvas on an image,as you can see,the size of this canvas is too large to exceed the GPU processing limit。Is there a better way that don't change size to solve this problem
