enquos is the first system to combine the
tracking of nutrition, fitness & health data so
that insights can be made between day to day
actions and health outcomes. It is completely
integrated, consolidating the functions of
multiple applications and tracking devices into
one secure platform while providing tools for
making smart choices.

Many weeks latency

Our automated
build system

12.
Fastlane
• Automates builds
• Allows multiple ‘lanes’ to be built
• Repeatable, scriptable builds
• An ‘API’ for iTunes Connect
• Takes the hassle out of the build and
deployment process

Things I’ve
learnt

iOS 8 → 9
Swift 1.2 → 2.0
Incompatibilities :(
Xcode 6.4 → 7

import Foundation
extension String {
public func toIso8601Date() -> NSDate? {
let formatter = NSDateFormatter()
formatter.timeZone = NSTimeZone(forSecondsFromGMT: 0)
formatter.dateFormat = "yyyy-MM-dd"
return formatter.dateFromString(self)
}
}

• Imposter syndrome is real
• Friendly communities rock
• Lack of virtualisation sucks
• Good documentation is great
• I still don’t understand Ruby
