There was a problem hiding this comment. non-blocking: Nothing checks two regions on the same side. Two left regions with maxX 50 and 40, in either order, should both give left 74. |

There was a problem hiding this comment. non-blocking: Could you mirror this on the right? A region at x 752, width 30 should give right 72. Right now changing the right side's |

There was a problem hiding this comment. These three close the surviving mutations (each verified to go red against the corresponding mutant): func testRegionStartingAtOnePoint_addsClearance() {
let region = CGRect(x: 1, y: 100, width: 40, height: 80)
XCTAssertEqual(insets(regions: [region]), UIEdgeInsets(top: 0, left: 65, bottom: 0, right: 47))
}
func testRightRegionWithinOnePointOfSafeAreaEdge_addsClearance() {
let region = CGRect(x: 752, y: 100, width: 20, height: 80)
XCTAssertEqual(insets(regions: [region]), UIEdgeInsets(top: 0, left: 59, bottom: 0, right: 72))
}
func testTwoRegionsOnRightSide_keepLargerClearance() {
let regions = [CGRect(x: 760, y: 100, width: 30, height: 80), CGRect(x: 790, y: 100, width: 5, height: 80)]
XCTAssertEqual(insets(regions: regions), UIEdgeInsets(top: 0, left: 59, bottom: 0, right: 64))

Worth naming the 1pt slack here (within 1pt of the screen edge counts as flush; up to 1pt past the safe area still counts as inside), since that is the part of the contract the suite only half-defends today.
