There is also SnapKit which I really like: https://github.com/SnapKit/SnapKit https://github.com/SnapKit/SnapKit box.snp_makeConstraints { (make) -> V

  And Masonry, if you're still on Obj-C (like me): https://github.com/SnapKit/Masonry https://github.com/SnapKit/Masonry [box mas_makeConstraints:^(MASConstraintMaker* make) { make.width.height.equalTo(50); make.center.equalTo(self.view); }];

  And cartography, which is my preference: https://github.com/robb/Cartography https://github.com/robb/Cartography constrain(button1, button2) { button1, button2 in button1.right == button2.left - 12 }

  Or while we're sharing, here's mine in Obj-C++ (although I never managed to extract it into a separate package): https://github.com/viewfinderco/viewfinder/blob/master/clients/ios/Source/UIView+constraints.h https://github.com/viewfinderco/viewfinder/blob/master/clien... [self addConstraints:box.anchorWidth == 50]; [self addConstraints:box.anchorHeight == 50]; [self addConstraints:box.anchorCenterX == self.view.anchorCenterX]; [self addConstraints:box.anchorCenterY == self.view.anchorCenterY];

  Came here to say the same thing. I've abandoned storyboards and nibs in favor of SnapKit and it hasn't let me down so far. It's one of the better libraries I've used on OS X and iOS.

  Or use NSLayoutAnchor, which was added in iOS 9 and OS X 10.10; [box.widthAnchor constraintEqualToConstant:50].active = YES; [box.centerAnchor constrantEqualToAnchor:self.view.centerAnchor].active = YES;
