Summary:
At least or x86_64 linux, it appears that you need position-independent
code is required in order to link against it. Otherwise you see errors
like this:
```
/usr/bin/ld: lib_sys.rlib(CSSLayout.c.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: lib_sys.rlib(CSSNodeList.c.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status
```
If I understand it correctly, you don't strictly need PIC for static libraries, but as soon as you want to link *other* dynamically linked library into it, it is required - which makes logical sense to me. Let me know if you want to enable this by default or leave it up to the developers to enable this if needed.

Summary: I found that if you move a subview to a different index, it would cause a crash in subsequent layout passes because the `CSSNodeRef` representing it was being re-inserted into the list. I spent a lot of time figuring out the best way to "diff" the view hierarchy from before and after, and I found the easiest implementation is also the most reliable. We can continue to optimize, but this is a great start.

Summary:
We currently have a bug in `UIView+CSSLayout.m` that you can repro in a scenario like this:
```
UIView *container = [[UIView alloc] initWithFrame:CGRectZero];
[container css_setUsesFlexbox:YES];
[container css_setFlexDirection:CSSFlexDirectionRow];
UIView *subview1 = [[UIView alloc] initWithFrame:CGRectZero];
[subview1 css_setUsesFlexbox:YES];
[subview1 css_setIncludeInLayout:NO];
[container addSubview:subview1];
UIView *subview2 = [[UIView alloc] initWithFrame:CGRectZero];
[subview2 css_setUsesFlexbox:YES];
[subview2 css_setIncludeInLayout:NO];
[container addSubview:subview2];
UIView *subview3 = [[UIView alloc] initWithFrame:CGRectZero];
[subview3 css_setUsesFlexbox:YES];
[subview3 css_setIncludeInLayout:YES];
[container addSubview:subview3];
[container css_applyLayout];
```
`subview3` (which is the only view whose is going to be included in layout calculation) is inserted at child index 2, instead of 0. This eventually can cause crash in CSSLayout.c because it will attempt access a child in the list which is null.

Summary:
When dealing with manual sizing in UIView's (or UIKit in general) we see a common pattern like so:
Below we have an example implementation of a view with two Labels that want to be stacked horizontally. If we don't pass a second string, we hide the second label and give up the available space to the first label. See below:
```
interface TitleSubtitleView : UIView
- (void)configureWithTitle:(NSString *)title subtitle:(NSString *)subtitle;
end
implementation {
UILabel *_titleLabel;
UILabel *_subtitleLabel;
}
....
- (void)configureWithTitle:(NSString *)title subtitle:(NSString *)subtitle {
_titleLabel.text = title;
if (subtitle.length > 0) {
_subtitleLabel.hidden = NO;
_subtitleLabel.text = subtitle;
} else {
_subtitleLabel.hidden = YES;
}
}
- (CGSize)sizeThatFits:(CGSize)size {
const CGSize titleSize = [_titleLabel sizeThatFits:size];
CGSize subtitleSize = CGSizeZero;
if (!_subtitleLabel.isHidden) {
subtitleSize = [_subtitleSize sizeThatFits:CGSizeMake(size.width - titleSize.width, size.height - titleSize.height)];
}
}
- (void)layoutSubviews {
[super layoutSubviews];
const CGSize titleSize = [_titleLabel sizeThatFits:size];
_titleLabel.frame = CGRectMake(0, 0, titleSize.width, titleSize.height);
if (!_subtitleLabel.isHidden) {
subtitleSize = [_subtitleSize sizeThatFits:CGSizeMake(size.width - titleSize.width, size.height - titleSize.height)];
_subtitleLabel.frame = CGRectMake(CGRectGetMaxX(_titleLabel.frame), 0, subtitleSize.width, subtitleSize.height);
}
}
```
The problem is with the CSSLayout framework, as long as your view is in hierarchy, it's going to be allocated space during layout calculation. The only way to fix the view above would be to completely remove it from view hierarchy if it isn't being used. The problem is that adding/removing views from hierarchy is much less performant than hiding.
As a result, we need a way to tell the CSSLayoutKit library that even though a view is in hierarchy, we don't want to include it in layout. With this diff, we could change the class to look like this:
```
interface TitleSubtitleView : UIView
- (void)configureWithTitle:(NSString *)title subtitle:(NSString *)subtitle;
end
implementation {
UILabel *_titleLabel;
UILabel *_subtitleLabel;
}
....
- (void)configureWithTitle:(NSString *)title subtitle:(NSString *)subtitle {
_titleLabel.text = title;
_subtitleLabel.text = subtitle;
const BOOL subtitleHasText = subtitle.length > 0;
_subtitleLabel.hidden = !subtitleHasText;
[_subtitleLabel css_includeInLayout:!subtitleHasText];
}
- (CGSize)sizeThatFits:(CGSize)size {
const intrinsicSize = [self css_intrinsicSize];
return CGSizeMake(MIN(size.width, intrinsicSize.width), MIN(size.height, intrinsicSize.height)));
}
- (void)layoutSubviews {
[super layoutSubviews];
[self css_applyLayout];
}
```

Summary: When I try to use this in practice, I have come to realize that css_sizeThatFits will 99% return to you the constrainedSize that you pass it, thus making it useless. Instead, we replace it with a new API that will tell you the optimal size of the resolved layout. From this we can choose to use that size, or scale it down.
