update Swift 5

[Gareth-swifter]

I have updated project swift version to 5.0 from 3.0 on Xcode 10.2

When I tested project with Xcode 10.2 with iPhone XR 12.2 Simulator on test failured.

Failure Detailes.
Failured Location : Viewtests - testEmbedInNavigationController L144
Failured Test Code : XCTAssertEqual(spreadsheetView.adjustedContentInset.bottom, 0)
Result : XCTAssertEqual failed: ("34.0") is not equal to ("0.0") -

so, i changed the code with
Code: XCTAssertEqual(spreadsheetView.adjustedContentInset.bottom, viewController.view.safeAreaInsets.bottom)

all test passed on Xcode 10.2 with iPhone 7 (iOS 12.2) and iPhone Xr.
