Log is a general purpose logging solution, offering levels and filtering, and the ability to collect the log for alternate storage / forwarding to other services.
- Set a current level and domain restriction to filter the log output
- Includes a timestamp, file location, function name and line number in the log output
Install with Carthage or simply by dragging the Log.swift (and BasicLog.swift) file(s). Can also be installed with CocoaPods, but Log isn't listed in the official podspec, so you'll need to direct reference the repo. You can optionally use the BasicLog file or use it as an example of a domain and level system.
It's recommended that you start by using the provided BasicLogDomain and BasicLogLevel. This is best done by extending BasicLogDomain to specify your logging domains and the level for each dmain:
extension BasicLogDomain {
static let commonSpec: Log<BasicLogDomain, BasicLogLevel>.LoggerSpec = (domain: .common, level: .debug, logger: nil)
static let networkSpec: Log<BasicLogDomain, BasicLogLevel>.LoggerSpec = (domain: .network, level: .debug, logger: nil)
static let modelSpec: Log<BasicLogDomain, BasicLogLevel>.LoggerSpec = (domain: .model, level: .debug, logger: nil)
static let logStore = Log<BasicLogDomain, BasicLogLevel>(specs: [commonSpec, networkSpec, modelSpec])
public func log<T>(_ level: BasicLogLevel, _ object: T, filename: String = #file, line: Int = #line, funcname: String = #function) {
let logger = BasicLogDomain.logStore.log(self)
logger.log(level, object, filename: filename, line: line, funcname: funcname)
}
}
It's also useful to shorten the naming to make the call site simple and to make any custom domain configuration you setup in the future easy to use:
typealias DLog = BasicLogDomain
It's then as simple as:
DLog.common.log(.debug, "Hello world")
