Issues with SpriteKit in Xcode 7 and IOS 9 - objective-c

Question

My game app that was working perfectly fine on IOS 8 (built with Xcode 6) is all of sudden experiencing many issues when built using Xcode 7 with IOS 9.
Here is how the game used to look. (How it should look).
Here is it running on IOS 9 (broken)

LEVEL SELECT
The only issue with this view is the background image (blue gradient) appears and then fades away.
The background image is set up in the storyboard.
Most Images are coming from Images.xcassets folder.
All images are png.
Bitcode is off (if that makes a difference)
Any other code or images, just ask.
How can I fix this problem and get my game working properly again?

Answer 1

iOS 9 cares more about zPosition than iOS 8 did. In the past if you didn't set the zPosition iOS8 would do a really good job of assuming what you wanted. In iOS9 it doesn't care and will render it however it wants.
I have also noticed leaving it at zero is also very bad. For instance if you have a node at 0 and add a child with a zPosition of 0...they both are 0 and iOS9 will pick which it should render first. If I am correct this should get your top hud showing back up again.
if (self.topHud == nil) {
self.topHud=[SKShapeNode shapeNodeWithRect:CGRectMake(-2,self.frame.size.height-62,self.frame.size.width+2,64)];
self.topHud.fillColor=[UIColor clearColor];
self.topHud.strokeColor=[UIColor clearColor];
self.topHud.lineWidth=0;
self.topHud.zPosition = 100;//added zPosition
[self addChild:self.topHud];
UIColor *textColor=[self.level textColor];
self.scoreLabel=[SKLabelNode labelNodeWithFontNamed:#"Blow"];
self.scoreLabel.fontSize=20;
self.scoreLabel.alpha = 1;
self.scoreLabel.zPosition = 1;//added zPosition
self.scoreLabel.horizontalAlignmentMode=SKLabelHorizontalAlignmentModeRight;
self.scoreLabel.fontColor=textColor;
self.scoreLabel.position=CGPointMake(self.frame.size.width-8,self.frame.size.height-25);
self.score=0;
[self.topHud addChild:self.scoreLabel];
self.highScoreLabel=[SKLabelNode labelNodeWithFontNamed:#"Blow"];
self.highScoreLabel.fontSize=20;
self.highScoreLabel.alpha = 1;
self.highScoreLabel.horizontalAlignmentMode=SKLabelHorizontalAlignmentModeRight;
self.highScoreLabel.fontColor=textColor;
self.highScoreLabel.position=CGPointMake(self.frame.size.width-8,self.frame.size.height-50);
self.highScoreLabel.zPosition = 1;//added zPosition
//self.highScore=0;
[self.topHud addChild:self.highScoreLabel];
Note 4 zPositions added. I hope that helps get things going in the right direction.
