I can't run Quasar 0.16 on iOS 9 with Safari 9

I got

SyntaxError: Unexpected use of reserved word 'let' in strict mode

I know that it relates to ES5 and Babel, but all that I tried didn’t make the success.

Does anybody know what exactly I must change to make this works?

Let’s see the code where this error is coming from.

 "/VnK": function (t, e, n) {
        "use strict";
        n.d(e, "a", function () {
            return u
        });
        let r = Object.prototype.toString, i = Object.prototype.hasOwnProperty, o = {};

        function a(t) {
            return null === t ? String(t) : o[r.call(t)] || "object"
        }

        function s(t) {
            if (!t || "object" !== a(t)) return !1;
            if (t.constructor && !i.call(t, "constructor") && !i.call(t.constructor.prototype, "isPrototypeOf")) return !1;
            let e;
            for (e in t) ;
            return void 0 === e || i.call(t, e)
        }

        function u() {
            let t, e, n, r, i, o, c = arguments[0] || {}, l = 1, h = arguments.length, d = !1;
            for ("boolean" === typeof c && (d = c, c = arguments[1] || {}, l = 2), Object(c) !== c && "function" !== a(c) && (c = {}), h === l && (c = this, l--); l < h; l++) if (null !== (t = arguments[l])) for (e in t) n = c[e], r = t[e], c !== r && (d && r && (s(r) || (i = "array" === a(r))) ? (i ? (i = !1, o = n && "array" === a(n) ? n : []) : o = n && s(n) ? n : {}, c[e] = u(d, o, r)) : void 0 !== r && (c[e] = r));
            return c
        }

        "Boolean Number String Function Array Date RegExp Object".split(" ").forEach(t => {
            o["[object " + t + "]"] = t.toLowerCase()
        })
    },

I tried to change let to var manualy, but broke js and got wrong token >
P.S.: This wrong token is also there in last lines. So it means that js is still in es6, not es5.

You push me on god way. I got minimized js, I’ll try to fix it manualy again in formated mode.
I thought that it is Babel setup problem, and I need to add something special to it. I’ve tried targets: { 'safari': 9 } but it gives nothing.

@Hawkeye64 Thank to you for your other answer (Upgrading v0.16 to v0.17) it helps me somehow.
I just added new quasar-cli@0.17.19 to dependencies and Babel works well now.

If you are interested in updating to Babel 7.x (which I have done), there is a great tool here: https://github.com/babel/babel-upgrade
