使用Zip3Sequence從我對這個問題的答案：http://stackoverflow.com/questions/40517760/is-there-a-zip-function-to-create-tuples-with-多於2個元素 – Alexander

let a = ["a1","a2","a3"] 
let b = ["b1","b2","b3"] 
let c = ["c1","c2","c3"] 

var merged: [String] = [] 

(0..<max(a.count, b.count, c.count)).forEach { 
    if $0 < a.count { merged.append(a[$0]) } 
    if $0 < b.count { merged.append(b[$0]) } 
    if $0 < c.count { merged.append(c[$0]) } 
} 
merged // ["a1", "b1", "c1", "a2", "b2", "c2", "a3", "b3", "c3"]
