Installation

use cocoapod

pod 'XConstraintKit', :git => '[email protected]:Ajaya1000/XConstraintKit.git', :tag => 'v1'

use SPM

add this library using this [email protected]:Ajaya1000/XConstraintKit.git

Uses

Activate constraint for childView with superView using the function func activate(with superView: ExpressibleByAnchors? = nil, @XLayoutConstraintBuilder constraints: (XLayoutConstraintMaker) -> [XLayoutConstraint])

self.childView.activate(with: superView) { xc in
    xc.leading
    xc.trailing
    xc.top
    xc.bottom
}

ExpressibleByAnchors are conformed by UIView & UILayoutGuide

for xc.leading => attr1 = .leading, attr1 = .leading for xc.leading.withTrailing => attr1 = .leading, attr1 = .trailing

so on like that

XLayoutConstraint has function to set constant, priority and multiplier.
