Error Domain=NSURLErrorDomain Code=-1200 해결하기

웹으로는 잘 보이는 API가 시뮬레이터로는 접근이 불가능한 문제가 발생했다.

이러한 에러가 발생했다.

SSL 오류가 발생했기 때문에 서버에 안전하게 연결할 수 없다고 한다.

해결방법

앱 폴더에 들어가면 Info.plist라는 파일이 존재한다

<변경전>

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>CFBundleURLTypes</key>
	<array>
		<dict>
			<key>CFBundleTypeRole</key>
			<string>Editor</string>
			<key>CFBundleURLSchemes</key>
			<array/>
		</dict>
	</array>
</dict>
</plist>

이러한 기존의 Info.plist 파일을

<변경후>

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>CFBundleURLTypes</key>
	<array>
		<dict>
			<key>CFBundleTypeRole</key>
			<string>Editor</string>
			<key>CFBundleURLSchemes</key>
			<array/>
		</dict>
	</array>
	<key>NSAppTransportSecurity</key>
	<dict>
		<key>NSAllowsArbitraryLoads</key>
		<true/>
	</dict>
</dict>
</plist>

이렇게 

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

이 부분만 추가해주면 성공적으로 불러와지는 것을 볼 수 있다.
